The charger won't break, but it won't charge either. Because the charger detects whether the battery is fully charged, it detects the battery voltage feedback.
48v battery, the full charge voltage should reach 51v or so, more than this voltage, the charger detects, it will be fully charged. Therefore, use a 48v charger to charge a 60v battery, and if it does not charge, the charger automatically switches to a fully charged state and stops working.
Extended data
48V new battery requires charger parameters, the highest voltage 58.5-59.7, not less than 58V, lower than 58V cause insufficient charging, higher than 59.7V May cause charging does not turn the lamp. The turning lamp current is about 0.4-0.7A, and the actual voltage is about 55.5V, which is lower than 50V, resulting in insufficient charging and long-term battery loss.
Select the correct charging voltage. If the charging voltage is too high, it will cause the initial charging current to be too large, which will cause plate bending, a large number of active substances to fall off, and the battery temperature rise is too high. Too low will cause insufficient battery charging, resulting in reduced capacity and shortened life. The terminal voltage of the charged battery must be identical.
